AI Technical Summary

Benefits of technology

The present invention relates to an emergency elevator that can quickly rescue patients and keep passengers safe from harmful gases by keeping the interior of the elevator car clean. Additionally, it can quickly remove flames to prevent passengers from being burned and enable rescuers to perform emergency cleaning and treatment inside the elevator car.

Problems solved by technology

When a fire occurs in a high-rise building, it is difficult to safely evacuate people on a fire-occurring floor and upper floors thereof due to the harmful gases, smoke and flames generated by the fire.

Since the fire occurring in such a high-rise building has a characteristic that it spreads instantaneously, it is not easy to complete the evacuation within the initial effective time.

In particular, the elderly, pregnant women and patients in medical care facilities are experiencing difficulties in evacuation, which may become a cause of damage to the people in case of fire.

However, in case of a fire in a high-rise building, the elevator may often serve as a passage for a fire.

However, in actual fire scenes, harmful gases, smoke and flames generated by a fire may rapidly spread to fire zones or emergency stairs, whereby the fire zones or the emergency stairs may fail to function in some cases.

In addition, it is often impossible to evacuate using emergency stairs or a rooftop due to a fire that spreads along the outer wall of a building.

Moreover, the emergency elevator according to the current standard is insufficient in the performance of blocking smoke, heat and flames and safely operating when a fire occurs.

Furthermore, it is difficult for the conventional emergency elevator to expect complete sealing.

Accordingly, when power is not supplied from the emergency power supply device or when the capacity of the battery is exhausted, the emergency elevator does not operate and has a difficulty in blocking smoke or flames when a fire occurs.

Further, in the conventional emergency elevator, it is impossible to immediately cope with a case where a cage stops between the entrances of two floors or a case where a person in a cage cannot wait for external rescue due to an urgent emergency situation.

However, it is practically impossible for a child, a patient, a disabled person, an aged person, a pregnant woman or an injured person to escape through a small emergency exit provided on the ceiling of a cage.

It is also difficult for a rescuer to rescue a person through the emergency exit.
